PURPOSE: To facilitate fine working with a simple head construction while improving the discharge property by forming flying drops of a liquid by a discharge power generated when a heat energy generated from a heat generating body works on the liquid in a liquid chamber.
CONSTITUTION: Heat generating elements 2 for generating ink discharge pressure are arranged in matrix on a substrate 1 made of glass or the like and a wiring pattern is formed by photo-lithography of an electroconductive film. Then, a member 3 which serves as a wave barrier while as a support for an orifice plate, a member 5 for forming a liquid chamber 8 therewith and glass or the like cut properly are joined together with an adhesive or the like to form a thermal action parts 81W89 which are driven independently. Then, an orifice plate 6 with an orifice hole 7 made by cutting and photoetching glass or the like is bonded on the substrate 1 with an adhesive or the like. This enables fine working while facilitating the adjustment of the thickness of the wall composing the thermal action part thereby ensuring a high discharge property.
